They are formed by the limestone being dissolved by ground-water seeping through the limestone's joints and other fissures.
Limestone caves are sometimes called solution caves because they are formed through a process called solution weathering. This occurs when water containing carbon dioxide dissolves the limestone rock, creating cave systems over time. The dissolved limestone is carried away in the form of a solution, hence the term "solution cave."
A large cave is called a cavern. These typically form in karst regions from the dissolution of soluble rocks such as limestone. Caverns can vary greatly in size, with some containing vast chambers and intricate formations like stalactites and stalagmites.
The limestone formation that is dripped from the ceiling of a cave and forms a peak or column is called a stalactite. Stalactites are typically formed from the slow deposition of mineral-rich water, such as calcium carbonate, which drips down from the cave ceiling over time.
Limestone is a porous and easily eroded rock that dissolves in acidic water. Over time, rainwater and underground water create networks of caves in limestone through a process called chemical weathering. The dissolution of limestone by water forms cave systems with unique formations such as stalactites and stalagmites.
A cave system - as simple as that. :-) Sometimes the system is named as So-&-So Cavern, especially if part of it has been modified to form a show-cave, but the formal and most used term is still "cave".
Ellison Cave was formed by the erosion of the rock by water over millions of years. The cave was created as groundwater seeped through the limestone bedrock, dissolving and creating intricate passageways underground. Over time, the cave continued to grow and develop into its current size and complexity.

I'd probably call it a "sinkhole" instead. It may lead to a cave, but the depression itself is not a cave.
A sinkhole is the term used to describe a depression in the ground caused by a cave collapse. It can also be the result of acidic water dissolving limestone.
Limestone
it is a 'karst' cave, i.e. formed by the action of water on limestone.
From dissolution and erosion of limestone by acidic water over time.
